## Impresión

The majority of consumer printers are automatically supported by Xubuntu, as it uses the CUPS (Common UNIX Printing System) back-end. This includes support for driver-less WiFi/wired network printing with printers that support IPP Everywhere and Apple AirPrint. If your printer is not immediately supported by Xubuntu you may need to install additional software, such as Gutenprint (`printer-driver-gutenprint`) and IPP-USB (install). Gutenprint extends CUPS by providing support for printers seen less often in end-user consumer settings, while IPP-USB is a more robust replacement to the default installation of the `ippusbxd` package. Normally CUPS and Gutenprint support is better adapted to Xubuntu than what will be available from the printer manufacturer.

### Managing Your Printer

Printer management can be done in the Printers settings dialog, which is accessible from the Hardware category of the Settings Manager, the Settings category of the application Applications Menu (Ctrl + Escape), and in the Application Finder (Alt + F3).

The Printers settings dialog allows you to add a new local printer (a printer directly connected to your computer through a USB, serial or printer port) or network printer (a printer connected on your network or a printer shared on the network through another computer). It also allows you to modify listed printers’ settings, such as renaming how they are labeled on your system, restarting, or disabling them. You can also share a printer with other computers on your network thereby making it a network printer. Depending upon the make and model of your printer, you can also check your printer’s consumables, such as toner or ink as well as paper, or send test print jobs.

### Add Printer

Setting up a new local printer should be as easy as plugging it into your computer and powering it on. The printer should be automatically detected and configured. Once it is successfully detected, a printer icon will appear in the notification area of the panel and a notification popup will appear with the text Printer is ready for printing.

If your printer was not detected, you will need to follow these steps:

- Open the Printers settings dialog.

- Click the Add button in the toolbar or Server → New → Printer in the menu to open the New Printer dialog.

- Select the appropriate Printer, Port, URI, Protocol or Network Printer entry in the Devices list on the left of the dialog. If your printer is not visible, you may need to click on the triangle next to “Find Network Printer” to expand the list of printers on your network.

- Where applicable, fill in any relevant details into the text fields and/or dropdown lists on the right of the dialog and then click the Forward button.

- If you are adding a local printer, your computer will search for it and install its drivers. If you are installing a network printer, you will go through additional steps of selecting the printer manufacturer, printer model and driver.

- You will then be prompted to enter a short name, description, and location of the printer.

- Press the Apply button to finalize the configuration of the printer.

- You will be prompted with a dialog asking Would you like to print a test page?

- If you press the Print Test Page button, a test page will print and you can verify if it printed correctly or you can press Cancel. Either way, your printer is ready to print.

If you are experiencing problems adding a printer with the steps above, you can try using the CUPS browser-based interface. It can be accessed at http://localhost:631/. Click the Administration menu item at the top of the page for options to add and find new printers. Do not make any changes in the Printers settings dialog or other system printer management utilities until you are finished using the CUPS browser-based interface. You may need to restart CUPS for it to reflect any changes that you make directly in the browser-based interface.

If the printer is directly connected to a Windows machine on your network, choose the Windows Printer via SAMBA entry from the Devices list. If you do not know the protocol or details of your network printer, you should consult the printer’s manual or ask your network administrator. Search the OpenPrinting database or check the Community Help Printer page for information on your printer.

### Share Printer

If you want to share your local printer with other computers on your network:

- Open the Printers settings dialog.

- Click Server → Settings in the menu.

- Enable the Publish shared printers connected to this system checkbox.

- Click the OK button.

Then go to your secondary Xubuntu installation and open the Printers settings dialog. Click the Add button in the toolbar, then expand the Network Printer option. The shared printer should appear below as the sharing computer’s IP address. You may need to first search for the IP address using the Find Network Printer option.

### Management Software

If you have an HP (Hewlett Packard) printer and would like additional software to manage it, you can install the HP Linux Imaging and Printing (HPLIP) GUI utilities (`hplib-gui`). These utilities include the HPLIP Toolbox application which will be found in the Settings category of the Applications Menu and the Others category of the Settings Manager. On supported inkjet printers, you will be able to monitor ink levels, check printer status, change page size and print quality, as well as clean the printer heads. On supported laser printers you will be able to monitor toner level, check printer status, change page size, and manage print quality. For all-in-one (multi-function) devices, you will be able to change fax settings and functionality. For more information about HPLIP click here.

### Printer Support

The OpenPrinting database stores information about printers, their drivers, and how well they are supported under Linux. If you are not sure about how well a printer is supported in a Linux environment check that database. It is also a good database to check before buying a new printer.

### Printer Drivers

If your printer doesn’t work automatically or you’d like to install the printer drivers and utilities from the printer manufacturer, here are some links to assist.

HP, Canon, Brother, Epson, Xerox, Lexmark

## Escaneo

Similar to Xubuntu’s support for printers, it also has plug and play support for many scanners, as many of them today come as part of multi-function devices. Scanner support on Linux is provided by the SANE project which maintains a list of supported scanners. Additional scanner support can be achieved with the installation of SANE-airscan (install), which allows driver-less network scanning with scanners that support Apple AirScan (eSCL) and Microsoft WSD.

### Using your Scanner

To begin using your scanner, open the Document Scanner or Simple Scan app, which is accessible from the Graphics category of the Applications Menu (Ctrl + Escape) and in the Application Finder (Alt + F3). Follow the next steps to scan a document, picture/image, etc.:

- Connect your scanner and power it on.

- Place what you want to scan on the scanner flatbed or feeder.

- Close the lid if you have a lid.

- Click the arrow to the right of the Scan button and choose the type of media you are scanning, Text or Photo.

- Click the Scan button to begin your scan.

### No Scanners Detected

Hay dos razones por las que puede obtener este mensaje:

- Your scanner is not automatically supported, which includes most parallel port scanners and Lexmark All-in-One printer/scanner/faxes.

- El controlador de su escáner no ha sido cargado automáticamente.

Es posible conseguir que su escáner funcione mediante la instalación de un controlador o la modificación de algunos archivos de configuración. Pida consejo en los foros de Ubuntu o en AskUbuntu.

To get some scanners working, you may need to plug the scanner in after the computer has booted.

### Instalación manual de un escáner

There are some scanners that have incomplete drivers from the SANE project. They can sometimes be used, but not all the features may work. For these scanners:

- Install the `libsane-extras` package.

- Run `pkexec mousepad /etc/sane.d/dll.conf` at the command line to open the SANE driver file for editing.

- Habilite el controlador correcto para su escáner eliminando el `#` situado delante del nombre del controlador. Puede que tenga que buscar en la web para averiguar qué controlador es el correcto

- Guarde el archivo y abra Simple Scan. Si todo va bien, su escáner funcionará ahora.
